DEVELOPMENT OF NEW APPROACHES TO THE TREATMENT OF HEMANGIOMAS IN EXPERIMENT

Area of Science:

• Biochemistry
• Developmental Biology
• Vascular Biology

Background:

• Angiogenesis, the formation of new blood vessels, is crucial for development but can lead to pathological conditions like hemangiomas when uncontrolled.
• Identifying endogenous regulators of angiogenesis is key to developing targeted therapies for vascular abnormalities.

Purpose of the Study:

• To investigate the role of endogenous factors in regulating angiogenesis.
• To evaluate a thermostable protein complex (TPC) from adult chicken liver as a potential inhibitor of capillary proliferation.
• To explore new therapeutic approaches for treating uncontrolled capillary growth.

Main Methods:

• Isolation of a thermostable protein complex (TPC) from adult chicken liver.
• Administration of daily TPC injections (200 µg) to an experimental hemangioma model (adolescent chicken comb) over 22 days.
• Histological assessment to quantify capillary changes in the papillary layer of the dermis.

Main Results:

• Daily TPC injections in adolescent chicken combs resulted in visible reductions in comb size and redness.
• Histological analysis confirmed that TPC significantly inhibited capillary growth within the highly vascularized dermal papillary layer.
• The thermostable proteins demonstrated a clear anti-angiogenic effect in the experimental model.

Conclusions:

• The thermostable protein complex isolated from adult chicken liver possesses significant anti-angiogenic properties.
• TPC effectively inhibits capillary proliferation in the adolescent chicken comb model of hemangioma.
• These findings suggest TPC as a promising candidate for developing novel treatments for conditions characterized by excessive capillary growth.
